I get an error when installing Socket.IO on Mac OS, how to solve?

Question

Node.js

There are 9 such errors in a row, I don’t understand what’s wrong, I reinstalled node-gyp, bufferutil, utf-8-validate, python

Answer 1

I think the problem is in node 4.0.0, I recommend installing nvm and using version 0.12

Answer 2

sudo npm install nvm
nvm download 0.12.7
nvm build 0.12.7
sudo npm install 0.12.7
node -v // Check node version
npm install socket.io -save

Answer 3

Not all libraries have yet been ported to node v.4.0, so it's too early to use it now, socket.io is one of those libraries...
